Bile duct injuries during laparoscopic cholecystectomy: primary and long-term results from a single institution

..To determine the usefulness and limitation of MRCP for detecting hepatolithiasis and biliary strictures, we compared the result of MRCP with that of percutaneous transhepatic cholangioscopy (PTCS) as the standard reference...

The substitution of endoscopic ultrasonography for endoscopic retrograde cholangio-pancreatography: implications for service development and training

..Therefore, the choice between EUS, MRCP and ERCP will become simplified: MRCP as the first option for diagnosis, EUS in doubtful cases needing sampling for pathology and ERCP as a therapeutic alternative to some surgical procedures...

Modification of a choledochoscope for extraction of difficult biliary stones

J J RothDepartment of Surgery, Medical College of Pennsylvania-Hahnemann University School of Medicine, Philadelphia, USAAm Surg 67:630-2. 2001

..This paper describes a simple method for dislodging difficult intrahepatic biliary stones: modification of a rigid choledochoscope to permit use of a biliary Fogarty catheter and Segura basket under direct visualization...

A cost-effectiveness analysis of biliary anastomosis with or without T-tube after orthotopic liver transplantation

..It is not only associated with fewer biliary complications, but also less costly than using choledochocholedochostomy over a T-tube. Randomized prospective studies are needed to confirm our results...

..In conclusion, biliary fistulas after HJA in LT or after SLT can be successfully treated by PTBD. The absence of enlarged intrahepatic biliary ducts should not be a contraindication for percutaneous treatment...

..Optical coherence tomography (OCT) is a high-resolution imaging technique that produces cross-sectional images in vivo. This is a report of the first use of OCT to acquire images of the biliary tree during ERCP...

..The objective of this study was to evaluate the clinicopathological features of patients with pancreaticobiliary maljunction, which was detected by intraoperative cholangiography in laparoscopic cholecystectomy...

..Traumatic bile leaks often result in prolonged morbidity and an increased length of hospital stay that requires multimodality management. Data on endoscopic management of traumatic bile leaks are scarce...

Multiplanar reformations and minimum intensity projections using multi-detector row CT for assessing anomalies and disorders of the pancreaticobiliary tree

..of laparoscopy, duodenoscopy and choledochoscopy has been accepted as a mini-invasive surgical therapy for bile duct diseases; but either endoscopic or laparoscopic therapy alone is disadvantageous in its narrow indications and in ..

..In this study, the significance of TFF family and deleted in the malignant brain tumor-1 (DMBT1), a putative receptor of TFF2, in the intrahepatic biliary tree was investigated in normal and diseased livers...

..We investigated the expression and localization of E-NPP1 and -3 in human inflammatory and neoplastic bile duct diseases. Immunohistochemically E-NPP1 was located on the apical cytoplasmic side of cancer cells, whereas E-NPP3 was ..
